Description

Technical Field

[0001] This utility model relates to the field of gear technology, and more specifically, to a split gear structure. Background Technology

[0002] Split gears are a type of gear design that is divided into two or more parts along the axial or radial direction. Their main purpose is to solve the problems of manufacturing, transportation and installation difficulties of large gears. They are particularly suitable for heavy machinery. The split parts are firmly connected into a whole by high-strength bolts through flanges and precision positioning structures. While ensuring transmission accuracy, it significantly reduces the manufacturing difficulty, transportation cost and on-site installation threshold of large gears.

[0003] Existing split gears are assembled and fixed to the bolt body through connecting bolt holes. When the gear is braked, there is a stress concentration point at the fixed position. Under long-term braking and impact, small displacements are prone to occur, which accelerates the wear and fatigue of the structure. Utility Model Content

[0004] The technical problem to be solved by this utility model is that the assembly and fixing surfaces of existing split gear assembly structures are easily affected by impacts, resulting in structural instability and wear. In order to solve the above problems, a split gear structure is provided.

[0005] The purpose and effect of this utility model are achieved by the following specific technical means: including a toothed ring, wherein the toothed ring is an inwardly concave hollow ring body, and an inner ring is formed in the toothed ring;

[0006] The toothed ring has a first clamping plate and a second clamping plate symmetrically arranged at the upper and lower ends of the inner ring, and a through shaft is fixed between the first clamping plate and the second clamping plate.

[0007] The toothed ring is encapsulated with a first disc holder and a second disc holder at both ends, and a positioning bolt is fixed between the first disc holder, the second disc holder and the inner ring. The first disc holder, the second disc holder and the first clamping plate and the second clamping plate are positioned and fixed by a through shaft.

[0008] A further preferred embodiment: a concave stepped surface is formed between the toothed ring and the inner ring, and the stepped surface overlaps with the first disc holder and the second disc holder.

[0009] A further preferred embodiment: the first tray and the second tray both have multiple stepped grooves arranged diagonally on their surface edges, and the stepped grooves are connected and fixed with the positioning bolts.

[0010] A further preferred embodiment: both ends of the inner ring stepped surface are fixed with I-shaped clamps, and the I-shaped clamps are threadedly engaged with the positioning bolts.

[0011] A further preferred embodiment: both the first tray and the second tray are fitted with flanges, and the ends of the flanges are provided with shaft openings.

[0012] A further preferred embodiment: a bearing portion is formed through the center of both the first clamping plate and the second clamping plate.

[0013] The beneficial effects of this utility model are:

[0014] This type of split gear structure uses a double-layer clamping plate and a plate frame to connect the assembly surface of the gear structure. The stepped surface structure of the gear ring structure improves the stability of the shaft core and the edge fixed end during axial movement. The distributed upper and lower connecting ends avoid stress concentration while ensuring the strength of the assembly structure. This effectively avoids the misalignment of the assembly structure during long-term braking and improves the strength and stability of the gear structure. Attached Figure Description

[0020] To better understand the above-mentioned objectives, features, and advantages of this utility model, the following description is provided in conjunction with the accompanying drawings. Figures 1-3 The present invention will be further described in detail below with specific embodiments. The following embodiments are merely examples for implementing the present invention. It must be noted that the disclosed embodiments do not limit the scope of the present invention. On the contrary, any modifications and refinements made without departing from the scope of the present invention are within the patent protection scope of the present invention.

[0021] A split gear structure includes a gear ring 1, which is an inwardly concave hollow ring body, and an inner ring 8 is formed in the gear ring 1.

[0022] The toothed ring 1 has a first clamping plate 3 and a second clamping plate 4 symmetrically arranged at the upper and lower ends of the inner ring 8, and a through shaft 12 is fixed between the first clamping plate 3 and the second clamping plate 4.

[0023] The toothed ring 1 is encapsulated with a first disc frame 2 and a second disc frame 5 at both ends, and a positioning bolt 10 is fixed between the first disc frame 2, the second disc frame 5 and the inner ring 8. The first disc frame 2, the second disc frame 5 and the first clamping plate 3 and the second clamping plate 4 are positioned and fixed by a through shaft 12.

[0024] The gear structure assembly end is as follows Figures 1 to 2 As shown, both the first clamping plate 3 and the second clamping plate 4 are fixed with pre-installed through shafts 12. During assembly, after positioning and docking, they are fixed by pressing and inserting inward to axially assemble and fix the first clamping plate 3, the second clamping plate 4 and the end of the toothed ring 1. Then, the first plate frame 2 and the second plate frame 5 are covered and sealed to the end of the toothed ring 1. Finally, the positioning bolt 10 is inserted between the toothed ring 1 and the first plate frame 2 and the second plate frame 5.

[0025] Compared to traditional split gear structures, this structure uses the combination of inner end shaft cores to fix the mounting plate on its assembly surface, and uses positioning bolts 10 inserted through the outer edge to fix the upper and lower steering wheel frames. By using assembly ends at different shaft surface positions, stress accumulation at local points is avoided, thereby improving the reliability of the gear structure while ensuring the overall stability of the gear structure.

[0026] Among them, a concave stepped surface is formed between the toothed ring 1 and the inner ring 8, and an overlapping surface is formed between the stepped surface and the first disc frame 2 and the second disc frame 5. The stepped surface and the overlapping surface of the inner ring 8 serve as the overlapping ends of the clamping disc structure and the disc frame structure, respectively, for the toothed ring 1 to assemble and position with it, and its concave groove ensures the accuracy and radial position stability when axially docking.

[0027] Furthermore, both the first tray frame 2 and the second tray frame 5 have multiple stepped grooves 7 arranged diagonally along their surface edges, and these stepped grooves 7 are fixed to the positioning bolts 10. Figure 2 As shown, multiple stepped grooves 7 arranged diagonally along the edge serve as the through-ends of the positioning bolts 10. The inner ring 8 is simultaneously provided with through holes that match the positions of the positioning bolts 10 and the stepped grooves 7, so that the positioning bolts 10 can be used to connect the first and second trays 2 and 5 distributed vertically during installation and fixing, thus ensuring the integrity and strength of the assembled structure.

[0028] Furthermore, I-shaped clamps 11 are fixed at both ends of the inner ring 8, and the I-shaped clamps 11 are threadedly engaged with the positioning bolts 10. The inner surface of the inner ring 8 is further combined and fixed with the positioning bolts 10 through the structure of the I-shaped clamps 11, so as to improve the connection strength between the inner ring 8 and the positioning bolts 10.

[0029] Furthermore, both the first plate frame 2 and the second plate frame 5 are fitted with flanges 6, and the ends of the flanges 6 are formed with shaft openings. The structure of the flanges 6 and the shaft openings corresponds to the installation method of the split gear mounting part, so as to adapt to the bearing shaft body to be inserted to the shaft opening end, or to assemble the gear by fixing it through flange connection of the flanges 6.

[0030] Based on the above, a bearing portion 9 is formed through the center of both the first clamping plate 3 and the second clamping plate 4. The bearing portion 9 cooperates with the shaft opening on the flange 6 as the through end of the shaft body for subsequent gear assembly and fixing.

[0031] During installation, pre-installed through shafts 12 are fixed on both the first clamping plate 3 and the second clamping plate 4. During assembly, after positioning and docking, they are fixed by pressing and inserting inward to axially assemble and fix the first clamping plate 3, the second clamping plate 4 and the end of the toothed ring 1. Then, the first plate frame 2 and the second plate frame 5 are covered and sealed to the end of the toothed ring 1. Finally, the positioning bolt 10 is inserted between the toothed ring 1 and the first plate frame 2 and the second plate frame 5.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
